How do you use this part?

Because many of us would like to learn how to effectively use more of the parts in the NXT kit, I'm going to start by asking you, our readers and bloggers, to share how and when you would use this part---the TECHNIC Knob Wheel. If you include pictures (which I hope you will), please make them close-up shots.

Yes they are GREAT at 90* changes of angle or 45*. I use them only now. Thet are wonderfull and MUCH stronger as well for this. My bipeds use them X6 uses three sets. to look at it many might think its not very good but it might be the strongest gear Lego made when in a 90* set up.

Back in the old RCX days we used those as part of a homemade rotation sensor. The knobs are perfect for pressing the button on a touch sensor and you got 8 counts per revolution. Half as good as the rotation sensor.

bah, back in MY day, we didn't even have knob wheels, had to make our own contraption to press the button on a touch sensor to count rotations. You crazy kids and your new-fangled built-in rotation sensors.

We had to build our own touch sensor with filthy cracked LEGO beams cut out from a brown paper bag with LEGO advertising on it.Which we got for working twenty-nine hours a day down mill and pay mill owner for permission to come to work!

But you try and tell the young people today that... and they won't believe ya'.
